I've known of him for years, but sadly, knew very little about him. It's a drawback of having not been to a con yet I guess. I 1st heard of him when he followed my Livejournal page 4 years ago. In recent days, I've been seeing just how loved he really is and I think this quote would be the best to place for his passing:
"Remember, a heart is judged not by how much you love, but by how much you are loved by others."
-The Wizard in The Wizard of Oz
Rest in peace Panda Guy.
